yesterday my Kindle Touch stopped working. Well, for the most part at least, that is I cannot read e-books on it right now. The home screen stopped showing up, it's just white emptiness. No matter how often I restart it, the home screen just does not load. The menu button and the book search do not work.

But the Kindle store button and getting into the browser (via Wikipedia in the search bar) do work. Browsing works, enabling and disabling wifi in the browser work. USB file mode works. Sometimes my device name shows up in the status bar, sometimes not. Sometimes the clock shows the proper time, sometimes 1:00 AM. Battery is full, charging still works.

It looks like just "framework" (Java-based part of UI) didn't get load properly. Maybe problem with full /var/local or some other "minor" inconvenience?

Post your logs (here in spoiler or, better, into some pastebin serivice). To get logs, execute command ;dm at search field, then look for them in USB drive.
